DIE-BLOCK.

Specification of Letters Patent. Application filed September 12, 1911. Serial No. 648,898.

Patented Aug. 13, 1912.

To all whom it may concern:

Be it known that I, RICHARD Lns'rnn VIL- oox, a citizen of the United States, residing at Waterbury, in the county of. New Haven and State of Connecticut, have invented certain new and useful Improvements in Die- Blocks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates 'to .new and useful improvements in die blocks, referring more particularly to a block for holding the dies in a header, and has for its object, among other things, to construct such a block, with readily detachable parts, so as to allow convenient and quick access to the dies without removal of the entire, block from the machine. I

To these, and other ends, my invention consists in the die block, havin certain details of construction and combinations of parts, as will be hereinafter described and more particularly pointed out in the claims. Referrin to the drawings, in which like nifmerals of reference designate like parts in the several figures; Figure 1 is a front elevation of'my improved die block with the dies and backing blocks shown in broken lines; Fig. 2 is a plan view; and Fig. 3 is a side elevation thereof.

Heretofore the die blocks for heading machines of that type wherein the dies are movable therein have been so constructed that access to the dies'could only be'had by removing the entire block from the machine,

' and as the block is both heavy and cumbersome, it has always been a matter of much labor to remove it, and in practice is usually accomplished with the aid of a' block and falls. Its immense size and Weight has also made it diflicult. to readily adjust the dies and the parts connected therewith when the block is replaced in the bed.

In my'improved block it is only necessary to remove a portion thereof to gain access to the dies and filling blocks, and the removable part is of comparatively small bulk and wei ht as compared with that of the entire bloc r, and is removed by hand with little or no labor.

' known to the art, and is substantially L shape in side elevation (as shown in Fig. 3), and the cap member 2, which is secured to one face of the. body member 1 by the bolts 3. This cap, when secured in place, leaving an open space between the horizontal'porof thecap, within which are mounted the dies, backing blocks and filling blocks, all being held against endwise movementby the plates 6 secured by the screws 7 In the body bushing 11. tion of the several dies, backing and filling blocks are as usual in this type of machine, and the dies are moved apart by the usual separators 8, shown by broken lines in Figs. .1 and 3, that are slidably mounted in the downwardly by the pressure of a spring (not shown) secured vto a fixed part. Suitably hardened plates 55 are secured to the body member and cap so as to take the 'wear of the dies.

IViththe die block as herein shown and described, access to the dies and blocks is conveniently and quickly had by simply -loosening the nuts 10 upon the boltsv 3 and moving the cap away from the body member 1, which is accomplished without disarranging .i the relative position of the die block with the bed of the machine.

Minor details of the block may be varied within my inventioh, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of my invention as defined by the claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a die block, the combination with a body member, having two walls at substantially a right angle to each other; of a cap; and means connected with one of said walls for securing said cap thereto, so as to leave an open space between said cap and the other wall, within which the dies are mounted.

2. In a die block oft-hat type wherein the dies are mounted so as to be movable therein, the combination with a body member, having two walls at substantia lv alright angle t-ion of the body member and the underside member there is fixed the usual hardened The arrangement andtoperaholes 9 in the cap 2, and are normally moved to each other, one of said Walls supporting the dies, and the other being the cap wall; of one or more bolts connected with said body member and projecting through said cap wall at an angle thereto; and a cap separably secured to said cap wall by said bolts, so as to leave an open space between said cap and the die supporting wall Within which the dies are movable.

3. In a die block, the combination with the L shape body member 1; of the cap 2;

and bolts 3 secured in said body member so as to project through one wall thereof and over the other wall and passing through said cap, whereby said cap is secured to one of said walls so as to leave an open space between the other wall, lying at substantially a right angle thereto, and within which the dies are mounted.

In testimony whereof I affix my signature in presence of two witnesses.
